PURPOSE:To secure a proper air-fuel ratio all the time as well as to prevent a worsening of drivability and a backfire from occurring, by compensating a warm-up increment value of a fuel injection quantity with cooling water temperature in time of starting. CONSTITUTION:A fundamental fuel injection quantity taup is calculated by a fundamental injection quantity operational device according to the specified driving state parameter, and a warm-up increment value f0 is calculated according to engine cooling water temperature THW, while a compensation factor f1 is found according to cooling water temperature THWO in time of starting, compensating the warm-up increment value f0 with the compensation factor f1, and the fundamental injection quantity in time of warming up is controlled for compensation. With this constitution, even after starting from what kind of water temperature, a proper air-fuel ratio is secured whereby a backfire or the like is preventable from occurring. |
